<p><P>PROBLEM TO BE SOLVED: To provide a locking mechanism of an electrical connection box, with which operability at the time of locking and unlocking can be improved and a locking retaining force in a locking state can be improved. <P>SOLUTION: The mechanism is provided with a locking arm 51 which is projectively installed in a cantilever shape on an inner wall 18 of a component storing room of a box body in the electrical connection box and a locking projection 55 which is projectively arranged on a face confronted with a component in the component storing room of the locking arm. The locking arm is divided into a base end region 51a fixed to the inner wall in a length direction, tip regions 51c and 51d on a free end side, which interferes with the component and to which a depression force for an unlocking operation applies, and an intermediate region 51b in a prescribed length range between the base end region and the tip region. Warpage rigidity of the intermediate region 51b is set to be smaller than that of the base end region 51a and the tip regions 51c and 51d depending on the presence or absence of ribs 52 and 53. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
